Annotation of src/UPDATING, Revision 1.206

1.206 ! dholland 1: $NetBSD: UPDATING,v 1.205 2009/11/16 07:39:54 dholland Exp $
1.1 abs 2:
1.123 jmc 3: This file (UPDATING) is intended to be a brief reference to recent
4: changes that might cause problems in the build process, and a guide for
5: what to do if something doesn't work.
1.1 abs 6:
1.123 jmc 7: For a more detailed description of the recommended way to build NetBSD
8: using build.sh, see the BUILDING file.
9:
10: Note that much of the advice in this UPDATING file was written before
11: build.sh existed. Nevertheless, the advice here may be useful for
12: working around specific problems with build.sh.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.203 dyoung 19: 20091101:
1.205 dholland 20: After updating, it may be necessary to make the 'cleandir'
21: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
22: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
23: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 24:
1.202 mrg 25: 20091001:
1.206 ! dholland 26: On amd64 you must rebuild tools (to get the new binutils)
! 27: before building a kernel, or the build fails on cpufunc.S.
! 28:
! 29: 20091001:
1.202 mrg 30: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
31: symlink, failing the build. Delete the link, and the subdir
32: it is in, and retry your build.
33:
1.201 dsl 34: 20090718:
35: libc build changed so that strchr() provides the extra entry
36: point for index(). Update build of libc.a (and libc_pic.a)
37: may fail because the archive contains the unwanted index.o.
38: (Similarly for strrchr() and rindex().)
39:
1.198 mrg 40: 20090709:
41: Native Xorg was upgraded again. Builds will probably fail again
42: without a clean objdir, at least for src/external/mit/xorg.
43:
1.197 mrg 44: 20090616:
45: Native Xorg was upgraded. Builds will need a clean objdir for
46: src/external/mit/xorg. Upgrading a system from sets will not
47: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
48: subdirectory has been changed into a file, and this needs to
49: be manually "rm -r"'ed before installing xbase.tgz.
50:
1.195 perry 51: 20090501:
52: Several new functions were added to string.h/libc, and this
53: can cause autoconf problems during the tool build for people
54: who fail to clean out their tools objects properly. If you
55: note messages about stpcpy, stpncpy or strnlen accompanying a
56: failure during the tool build, clean out all your tools
57: objects and start again.
58:
1.194 mrg 59: 20090325:
60: The i386 port was switched to i486 default toolchain. This requires
61: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
62:
1.192 skrll 63: 20090126:
1.193 skrll 64: The __posix_fadvise50 system call changed assembly stub type. You need to
65: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 66: the old assembly stub.
67:
1.191 joerg 68: 20090202:
69: pkg_install now depends on the pkgdb cache for automatic conflict
70: detection. It is recommented to rebuild the cache with
71: ``pkg_admin rebuild''.
72:
1.184 christos 73: 20090110:
74: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
75: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 76: This is needed even in the MODULAR kernel because there is
77: conditionally compiled code in rtsock.c.
1.184 christos 78: 2. make sure build.sh completes and the binaries in a chroot work
79: before installing.
80: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 81: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 82: are installed properly, and start building libraries first libc
83: and libutil, install them and then continue building all the
84: libraries in src/lib and src/gnu/lib and install them. Once
85: the new libraries are installed, you can restart the build.
86: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 87: rebuild the required packages to update their shared libraries.
88: Any package you rebuild will require rebuilding all the packages
89: that depend on it.
1.186 christos 90: 5. Next time you run pwd_mkdb with the new binary, the file
91: will be upgraded and it will not be backwards compatible.
1.190 apb 92: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
93: lastlogx(5)) have been versioned, and there is a heuristic
94: for utmp. You are better off removing the old files after
95: upgrading. The automated clearing of /var/run during
96: boot, and the automated rotating of files in /var/log by
97: newsyslog(8), may mean that you do not have to remove the
98: files manually.
99: 7. The optional accounting file (/var/account/acct, see
100: accton(8)) has not been versioned, and will need to be
101: removed. The automatic rotation of the accounting file by
102: /etc/daily limits the bad consequences of failure to remove
103: the file.
1.196 dholland 104: 8. Application software that writes time_t to binary files on
105: disk will break or need attention. Most notably: if you are
106: using PostgreSQL < 8.4, you need to dump your databases,
107: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 108:
1.183 pgoyette 109: 20081219:
110: config(1) has been updated, and one of the files it creates -
111: swapnetbsd.o - has changed format. You need to rebuild config
112: (done automatically by build.sh) and then you need to rerun
113: config on all kernel configuration files before rebuilding those
114: kernels.
115:
1.181 cube 116: 20081205:
117: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
118: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
119: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 120:
1.179 tsutsui 121: 20081122:
1.182 tsutsui 122: On i386, various kernel options(4) in GENERIC including
1.180 wiz 123: file systems have been disabled and moved into kernel modules.
124: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 125: following files as well as a new GENERIC kernel:
126:
127: - build and install kernel modules from src/sys/modules
128:
129: - install the latest bootloader, which will load a module
1.180 wiz 130: for the file system from which the kernel is loaded automatically
1.179 tsutsui 131:
1.180 wiz 132: If you have to load your kernel from a file system which is not of
133: the same type as the root file system, you have to load the necessary
134: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 135:
1.178 lukem 136: 20080827:
137: If you built and installed a libc from sources between
138: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
139: which results in false errors reported by lint(1).
140: Since this breaks the libc build itself, manual help is
1.180 wiz 141: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 142: $ (cd lib/libc && make MKLINT=no dependall install)
143:
1.177 christos 144: 20080813:
145: MKDEBUG build was broken because the .depend files did not know
146: about .go files. You need to remove all .depend files and rebuild.
147:
1.200 dholland 148: 20080802:
149: A regression in binary compatibility for pthread_mutex_t has
150: been fixed. Unfortunately, the price is breaking compatibility
151: for -current.
152:
153: Threaded programs (using libpthread) and C++ programs (using
154: libstdc++) compiled after 20070907 and before 20080802 need to
155: be recompiled.
156:
157: One way to find affected pkgsrc packages:
158:
159: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
160: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
161:
1.175 simonb 162: 20080731:
163: WAPBL (metadata journaling support) has been added, but at this
164: time isn't backwards compatible with pre-WAPBL aware kernels
165: and userland (fsck_ffs in particular). Please make sure you
166: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 167: especially an uncleanly mounted journaled filesystem. WAPBL
168: also requires the super block to be in the UFS2 format. You
169: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 170:
1.174 lukem 171: 20080721:
172: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
173: isn't defined.
174:
1.173 freza 175: 20080531:
176: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
177: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
178: utility needs to be rebuilt and reinstalled as older binaries
179: won't work correctly. The following sequence of commands:
180:
181: $ (cd sys/sys/ && nbmake-$arch includes)
182: $ (cd sbin/drvctl/ && nbmake-$arch clean)
183: $ (cd sbin/drvctl/ && nbmake-$arch all)
184:
185: leaves new drvctl utility in sbin/drvctl build directory.
186:
1.172 lukem 187: 20080503:
188: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
189:
1.171 he 190: 20080521:
191: For a while, unprivileged UPDATE builds would fail to
192: succeed at the checkflist stage, complaining that
193: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
194: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
195: If you already hit this problem, update the .mk file,
196: remove ${DESTDIR}/stand/<arch>, and re-run the build.
197:
1.174 lukem 198: 20080303:
199: Linker warnings are now fatal if $WARNS>0.
200:
1.170 christos 201: 20080126:
202: The posix_fadvise system call has been changed from an assembly
203: stub, to a c file that calls an assembly stub. You need to
204: 'rm -f posix_fadvise.* .depend' in the libc build directory to
205: avoid using the old assembly stub.
206:
1.168 joerg 207: 20071209:
208: The acpiec(4) driver has been split into two attachments. If you
209: get ACPI errors before the attachment, please update your kernel
1.169 wiz 210: configuration file appropriately or see GENERIC for more details.
1.168 joerg 211:
1.166 xtraeme 212: 20071115:
213: The it(4) driver has been renamed to itesio(4) and the old port
214: argument specified in the kernel configuration file is not valid
215: anymore. The itesio(4) driver now uses the Super I/O address port
216: rather than the EC address port. Please update your kernel
1.167 wiz 217: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 218:
1.165 jmmv 219: 20071028:
220: The pccons(4) driver has been removed from the NetBSD/shark port.
221: You need to update any custom kernel configuration file you have
222: to remove any references to pccons (which includes removing the
223: now useless XSERVER option) and replace them with the correct
224: entries for the wscons driver. See the GENERIC configuration file
225: for more details.
226:
1.164 gdt 227: 20070913:
228: A latent bug in dhclient/dhcpd that caused it to be unable to
229: enumerate interfaces was fixed. The bug began to cause
230: problems after 20070911 when the kernel's SIOCGIFCONF
231: implementation was repaired. From 20070529 to 20070911 racoon
232: could not enumerate interfaces. (These are noted because
233: normal kernel/userspace version matching hygiene is not
234: sufficient to avoid this problem.) Ensure that both kernel
235: and userland are from after 20070913.
236:
1.163 joerg 237: 20070703:
1.199 dholland 238: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
239: calls the target-specific strip program, and the logic to pass
240: down STRIP from make has been removed. This requires a
241: re-installation of tools.
1.163 joerg 242:
1.161 dsl 243: 20070422:
244: The way OS emulations lookup filenames inside the emulation root
245: has been changed. Rather than modify the pathname (and copy back
246: to userspace) namei() and lookup() directly check the emulation
247: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 248: root file system will be relative to that file system - unless they
1.161 dsl 249: start /../ this is useful when the emulated root is a real install
250: that has such links.
251: This might affect symlinks that have been added to reference outside
252: the emulated root.
253:
1.160 jmcneill 254: 20070412:
255: The pckbc driver on sgimips IP32 has been removed. Use macekbc
256: instead. See the GENERIC32_IP3x kernel configuration for an
257: example.
258:
1.159 gdt 259: 20070319:
260: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
261: on many platforms due to incorrect flags settings. If you
262: updated and built after about 20070315, do "nbmake-$arch
263: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
264: rebuild of object files that might have been built
265: incorrectly, and ensure that you have at least
266: src/lib/libc/Makefile 1.130.
267:
1.158 dbj 268: 20070210:
269: src/sys/sys/{sa.h,savar.h} were removed.
270: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
271: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
272: will allow dependencies on those files to get get rebuilt
273:
1.157 apb 274: 20070209:
275: The threading model was changed when the newlock2 branch
276: was merged to NetBSD-current. If you boot with a new
277: kernel (version 4.99.10), then you also need a new pthread
278: library (/usr/lib/libpthread.so.0.7). If you boot with
279: an old kernel, then you need the old pthread library
280: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
281: the pthread library in sync, old threaded applications should
282: continue to work with an old or new kernel. Note that named(8)
283: is the only threaded application in the base system.
284:
1.154 he 285: 20061214:
286: Following the move of string_to_flags() and flags_to_string()
287: from the bin/ls/ sources to libutil, users doing UPDATE builds
288: will need to do a "make cleandir" in
289: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
290: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 291: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
292: as the installation images in distrib/
1.154 he 293: in order to excise stale references to the old stat_flags.h header
294: file in the ls sources -- stat_flags.h has been removed.
295:
1.152 christos 296: 20061108:
297: The configure script used in the src/tools/gcc compiler has been
298: changed to indicate that our libc has ssp support built-in and
299: does not depend on -lssp and -lssp-nonshared. You'll need to
300: make clean in src/tools/gcc first to rebuild the compiler.
301:
1.151 rpaulo 302: 20061009:
303: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
304: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
305:
1.150 bjh21 306: 20060814:
307: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
308: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
309: kernel configuration for an example. X servers from the last
310: few years should cope.
311:
1.149 christos 312: 20060703:
313: MPACPI is no more. We always configure PCI interrupts using ACPI
314: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
315: to ACPI_SCANPCI. Thanks to work from fvdl.
316:
1.148 dogcow 317: 20060627:
318: socket(2) has changed, and its system call has been versioned.
319: For userlands with the old version of socket(2), make sure that
320: your kernel has 'options COMPAT_30' set, or else 'bad system call'
321: errors will result.
322:
1.1 abs 323: Hints for a more successful build:
324: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 325: Use build.sh, but do not use its "expert mode":
1.132 jmmv 326: This will automatically build the tools in the
1.123 jmc 327: correct order, and it will keep the tools and the
328: new build products from interfering with the running
329: system. This will allow you to ignore most of the
330: other advice in this file.
1.2 mrg 331: Build a new kernel first:
332: This makes sure that any new system calls or features
333: expected by the new userland will be present. This
334: helps to avoid critical errors when upgrading.
1.1 abs 335: Use object directories:
336: This helps to keep stale object
337: files from polluting the build if a Makefile "forgets"
338: about one. It also makes it easier to clean up after
339: a build. It's also necessary if you want to use the
340: same source tree for multiple machines.
1.123 jmc 341: To use object directories with build.sh:
342: a) invoke build.sh with the "-M" or "-O" options.
343: To use object directories without using build.sh:
1.1 abs 344: a) cd /usr/src ; make cleandir
1.2 mrg 345: b) Add "OBJMACHINE=yes" to /etc/mk.conf
346: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 347: d) cd /usr/src ; make build
1.2 mrg 348: Note that running "make obj" in a directory will create
349: in obj.$MACHINE directory.
1.1 abs 350: Build to a DESTDIR:
1.123 jmc 351: This helps to keep old installed files (especially libraries)
352: from interfering with the new build.
353: To build to a DESTDIR with build.sh, use the "-D" option.
354: To build to a DESTDIR without using build.sh, set the DESTDIR
355: environment variable before running make build. It should be
356: set to the pathname of an initially empty directory.
357: Problems: if you do not use build.sh, you might need to
358: update critical utilities without using DESTDIR since
359: nothing is executed from what is installed in DESTDIR.
360: (See critical utils, below.)
1.1 abs 361: Build often:
362: This keeps critical utilities current enough to not choke
363: on any other part of the source tree that depends on up to
1.123 jmc 364: date functionality. If you use build.sh, you should not have
365: this problem.
1.1 abs 366:
367: What to do if things don't work:
368: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
369: When things don't work there is usually a few things that commonly
370: should be done.
371: 1) make includes
372: This should be done automatically by make build.
373: 2) cd share/mk && make install
374: Again, automatically done by make build.
375:
376: Failsafe rebuild of a small part of the tree:
377: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
378: To make sure you rebuild something correctly you want to do
379: something like the following:
380: 1) Make sure the includes and .mk files are up to date.
381: 2) Make sure any program used to build the particular
382: utility is up to date. (yacc, lex, etc...)
383: 3) cd ...path/to/util...
384: make cleandir
385: rm ...all obj directories...
386: make cleandir # yes, again
387: make obj
388: make depend && make
389:
390: Failsafe rebuild of the entire tree:
391: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
392: If you really want to make sure the source tree is clean and
1.2 mrg 393: ready for a build try the following. Note that sourcing /etc/mk.conf
394: (a make(1) Makefile) in this manner is not right, and will not work
395: for anyone who uses any make(1) features in /etc/mk.conf.
